Abstract

The invention relates to a method for determining a side slip angle (beta) during cornering of a motor vehicle, the following input variables being sensed and linked with one another via a mathematical vehicle model (15) with the assumptions of the linear bicycle model: - a predefined or measured position of the centre of gravity (S) between a front axle (2) and a rear axle (3), - the current vehicle velocity (v) of the motor vehicle (1), - a current cornering movement variable (psi point, a) of the motor vehicle, - the current steering angle (delta) at the front axle. To simplify the determination of the side slip angle during cornering, the side slip angle is determined assuming that the difference between the side slip angle (beta) and the Ackermann side slip angle (beta0) is proportional to the difference between the Ackermann angle (deltaA) and the steering angle (delta). The actual side slip angle (beta) is deduced from the relationship between the measured steering angle (delta) and the Ackermann angle (deltaA), by means of the proportionality relationship of the Ackermann side slip angle (beta0) theoretically present while driving through the same curve without slip.

Abstract

The invention relates to a method for the emergency braking of an ego-vehicle, in which method an environment sensing system of the ego-vehicle, which is traveling in a direction of travel, senses a front space in front of the ego-vehicle. When an object is detected in the front space, it is determined that a reliable target detection situation (ZES) exists (St3) if at least the following target detection situation criteria (ZES-K1-3) are met: the detected object is a vehicle in front traveling in the direction of travel; the vehicle in front is followed over a minimum following time period (tmin); in the minimum following time period, the same vehicle in front is followed. An autonomous emergency-braking-system system (AEBS) is provided, which is in an autonomous emergency-braking-system system readiness mode (AEBS-GM) during travel outside of an emergency braking situation (ES). When an emergency braking situation (ES) is determined outside of a reliable target detection situation (ZES), the autonomous emergency-braking-system system (AEBS) switches into an active autonomous emergency-braking-system system mode (AEBS-M) with an autonomous emergency-braking-system system cascade of a first driver warning (DW), subsequent partial braking (TB) and subsequent emergency braking (EB). When an emergency braking situation (ES) is determined in a reliable target detection situation (ZES), the autonomous emergency-braking-system system (AEBS) switches into an active autonomous emergency-braking-system system following mode (AEBS-FM) with emergency braking (EB) without prior driver warning (DW).

Abstract

The invention relates to a piston-cylinder assembly (1), comprising a cylinder housing (3), in which a main piston (2) and at least one dragg piston (11, 12) are axially slidably accommodated.

The drag piston (11, 12) is axially slidably guided on a cylindrical outer lateral surface (38) of the main piston (2), which outer lateral surface extends laterally to a circular piston flange (10), which acts as an axial abutment and which points radially outward.

A displacement limiter (28) for limiting the displacement of the drag piston (11, 12) is arranged or formed on the cylinder housing (3). When pressure is applied, the drag piston (11, 12) drags the main piston (2) along by means of the pushing section (13, 14) until the drag piston (11, 12) hits the displacement limiter (28). In order to achieve a small total axial length, according to the invention, the piston flange (10) has an axial recess (30, 31) and the pushing portion (13, 14) of the drag piston (11, 12) is geometrically designed in such a way that the pushing portion (13, 14) can interlockingly plunge into the associated recess (30, 31).
